Introduction:
Losing weight intentionally through healthy diet and exercise is often a positive goal. However, sudden or unexplained weight loss especially without changes in eating habits or physical activity can be a cause for concern. Many people ignore unexpected weight loss, assuming it is due to stress or lifestyle changes, but in some cases, it may indicate an underlying medical condition that needs timely attention.
At Santosh Multispecialist Hospital, Faridabad, doctors often see patients who report sudden weight loss along with fatigue, weakness, or other symptoms. With a multispeciality team and modern diagnostic facilities, Santosh Multispecialist Hospital, Faridabad focuses on identifying the root cause and providing appropriate treatment.
This article explains what sudden weight loss means, its common and serious causes, and when you should seek medical help.
What Is Sudden Weight Loss?
Sudden weight loss is generally defined as losing 5% or more of your body weight within 6–12 months without trying. For example, if a person weighing 70 kg loses 4–5 kg without dieting or exercising, it is considered unexplained weight loss.
Doctors at Santosh Multispecialist Hospital, Faridabad emphasize that while mild fluctuations are normal, significant and rapid weight loss should never be ignored.
Common Causes of Sudden Weight Loss
1. Stress, Anxiety, and Depression
Mental health plays a major role in appetite and metabolism. Chronic stress, anxiety, or depression can lead to:
-
Loss of appetite
-
Reduced calorie intake
-
Hormonal imbalance
This can result in unintentional weight loss. At Santosh Multispecialist Hospital, Faridabad, physicians assess both physical and emotional health when evaluating unexplained weight loss.
2. Digestive Problems
Conditions affecting digestion can prevent the body from absorbing nutrients properly.
Common digestive causes include:
-
Gastritis
-
Peptic ulcers
-
Chronic diarrhea
-
Irritable bowel syndrome (IBS)
-
Malabsorption disorders
Such issues may lead to weight loss along with abdominal pain, bloating, or loose stools.
3. Thyroid Disorders
An overactive thyroid (hyperthyroidism) speeds up metabolism, causing the body to burn calories faster than normal.
Symptoms may include:
-
Weight loss despite normal or increased appetite
-
Palpitations
-
Sweating
-
Anxiety
-
Tremors
Doctors at Santosh Multispecialist Hospital, Faridabad often recommend blood tests to check thyroid function in patients with sudden weight loss.
4. Diabetes
Uncontrolled diabetes can lead to weight loss, especially when blood sugar levels remain high.
Warning signs include:
-
Increased thirst
-
Frequent urination
-
Fatigue
-
Blurred vision
Early diagnosis and treatment at Santosh Multispecialist Hospital, Faridabad can help prevent complications related to diabetes.
5. Chronic Infections
Long-term infections can cause gradual but significant weight loss.
Examples include:
-
Tuberculosis (TB)
-
Chronic urinary infections
-
Persistent respiratory infections
These conditions often cause fatigue, fever, or night sweats along with weight loss.
6. Poor Appetite in Older Adults
In elderly individuals, reduced appetite due to aging, medications, dental problems, or underlying illness can result in sudden weight loss. Doctors at Santosh Multispecialist Hospital, Faridabad carefully evaluate seniors to identify reversible causes.
Serious Medical Causes of Sudden Weight Loss
7. Cancer
Unexplained weight loss is sometimes an early sign of cancer. Tumors can alter metabolism, suppress appetite, or increase energy consumption.
Possible warning signs include:
-
Persistent fatigue
-
Pain
-
Lumps or swelling
-
Changes in bowel habits
While weight loss alone does not mean cancer, doctors at Santosh Multispecialist Hospital, Faridabad stress the importance of thorough evaluation to rule out serious conditions.
8. Chronic Lung or Heart Diseases
Advanced lung or heart conditions may lead to weight loss due to increased energy demand and reduced appetite. Breathlessness, chest discomfort, or exercise intolerance may be present.
Multispeciality care at Santosh Multispecialist Hospital, Faridabad ensures such patients receive timely diagnosis and treatment.
9. Autoimmune Diseases
Conditions like rheumatoid arthritis or other autoimmune disorders can cause chronic inflammation, leading to weight loss and fatigue.
10. Medication Side Effects
Certain medicines may reduce appetite, alter taste, or cause nausea, leading to unintended weight loss. Reviewing medication history is an important part of evaluation at Santosh Multispecialist Hospital, Faridabad.
